Question

Label each target to indicate if the interaction between the molecules inside the rectangle contributes to surface tension (t), adhesion (a), or cohesion (c). note that one target should be left blank because the molecules inside that rectangle are not involved in any of these interactions.

Answer 1

Surface Tension usually occur with the air-water interfaces. The breakage of the surface of the water. The curvature of the surface is usually reduced because of the hydrogen bonds that pulls the water molecules at the surface together. Cohesion tends to keep water molecules away from the surface from separating. Adhesion keeps the water to stick on hydrophilic surfaces.
